Invites are earned on Hedgehog through positive community engagement. This means receiving reactions to topics of conversation, participating in chatrooms, and not getting your content removed via community moderation. The people you invite to Hedgehog will also impact your ability to invite others. If they are hurting the community or being a nuisance in conversation, you will be less likely to earn invites. Every account has a rating, and periodically, Hedgehog will issue more invites to people who hold a better rating in the community.
